SAMUEL GRIFFIN, OF BATH, ENGLAND.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed February 1. 1906. Serial No. 299.035.

To all whom it may concern: Be it known that I, SAMUEL GRIFFIN, a subject of the Kingdom of Great Britain, and E resident of Kingston Iron I/Vorks, Bath, in the county of Somerset, England, engineer, have invented certain new and useful Iml provements in Suction Gas-Producers, for which I have applied for a patent in Great Britain, Patent No. 14,264, July 11, 1905, of which the following is a specification.

My invention relates to an improved means 5 of automatically regulating the supply of! fuel to suction gas producers, and the like.

Hitherto it has been usual to supply the i generator with fuel necessary to the production of gas at irregular intervals, varying acl cording to the required supply of gas, by means of apparatus operated by hand, thus necessitating constant attention, with the further disadvantage of proportional irregularity in the quantity and intensity of the in l candescent mass in said generator. According to my present invention I disi pense with said hand operated apparatus, and in its place I arrange any suitable form i of mechanical fuel feeder, or stoker, operated advantageously by means of a piston, diaphragm, or other equivalent device, such piston, diaphragm, or other equivalent device being connected in one arrangement of my 3 invention with the air inlet, or interior of the l generator, or parts connected therewith, and actuated by the partial vacuum formed therein during the suction of the engine. The maximum capacity of the said fuel feeder, or stoker, is adapted approximately to that nec- 3 essary for the maximum output of gas, gov- I erned by the maximum number of impulses in said engine at full power. It will be obvious that any less number of impulses than the maximum will proportionately diminish the mean movement of said fuel feeder or stoker, and thus proportionately diminish the mean amount of fuel supply.

According to another arrangement, said fuel feeder, or stoker may be operated by suitable mechanism connected with the en 1 gine, or parts thereof, 6. g., a piston operated by the exhaust may take the place of the aforesaid piston, diaphragm, or other equiv- 1 alent device, or movement may be communicated direct from the governor, or inlet Under certain conditions the supply of water for the formation of steam for the generator may be advantageously controlled siout of operating position.

taining piston B.

multaneously with that of the said fuel by means of suitable mechanism operated by said piston diaphragm, or other suitable device.

I do not confine myself to the details above described, these may be modified without departing from the nature of my invention.

In order that this invention may be clearly understood and more easily carried into practice, I have appended hereunto a sheet of drawings upon which I have illustrated the nature of my said improvements.

Figures 1 and 2 are front and side elevations of generator showing arrangement of mechanism for operating fuel feeder. Fig. 3 is a corresponding sectionthrough the feeding drum casing and hopper, showing arrangement of coal pockets in drum. Fig. 4 is a plan of feeding drum and operating mechanism, showing traversing screw for moving feeding drum and hopper into and Fig. 5 shows alternative arrangement of hopper and feeding f mechanism in which an endless screw or creeper, is substituted for the revolving drum. The same letters of reference refer to the same parts in Figs. 1, 2 and 3 and 4.

A gas generator. B motor cylinder con- C pipe from bottom of motor cylinder B communicating with exhaust of engine. D regulating cock. E jointed rod connecting piston of cylinder B with lever F. G spiral spring for returning piston to its normal position after each impulse. H ratchet wheel operated by pawl I. J worm attached to shaft K of ratchet wheel H. L worm wheel gearing with worm J. M clutch by means of which wheel L can be engaged with, or disengaged from, shaft N of feeding drum 0 working practically airtight in casing P. Q handwheel attached to shaft N for operating feeding drum 0 independently by hand. fuel supply. S opening from hopper to R hopper to contain pockets T, T, T, T, of feeding drum. U opening from pockets of feeding drum to in terior of generator. V handwheel for operating traversing screw W.

Referring to Figs. 1., 2, 3 & 4, the mode of operation is as follows :The pipe 0 being connected with the exhaust outlet of engine,

on opening the regulating cock D the pressure of the exhaust gases will raise the piston in motor cylinder B, thus imparting a rotator movement to the feeding drum 0 throug the train of mechanism E, F. H. I.

J. K. L, the return of the piston to its lowest or normal position being effected by the spring G which has been compressed by the up-stroke of the piston. The fuel contained in the hopper R passing into the pockets T, T, T, T, as the drum rotates, will thus be discharged through the opening U into the interior of the generator A, thus replenishing the fire therein contained. By disengaging clutch M the feeding drum 0 can be rotated by the hand wheel Q if required. The regulating cock D controls the pressure admitted to motor cylinder B and thus regulates the movement of the piston. The traversing screw is for the purpose of moving the feeding drum 0 and hopper R from its operating position, so that access may be had through the opening to the interior of the generator A when desired. The feeding drum and hopper may also be permanently fixed in positlon if desired, access to the interior of the generator being obtained through a separate opening with a movable cover as shown in Fig. 5.

It will be obvious that the amount of fuel discharged into the interior of the generator in a given time will be controlled by the number and intensity of the impulses received by the piston from the exhaust pressure of the engine with which it communicates.

Referring to Fig. 5, R is the fuel hopper closed by air tight cover R and communicating with the hollow casing P by means of the worm, or creeper 0. An air tight cover P closes the top of the casing P. A .worm wheel L gives motion to the worm or creeper O. The interior of the casing P communic-ates with the interior of the generator A.

The worm or creeper 0 takes the place of the feeding drum 0 previously described, and receives a rotatory movement through the medium of suitable mechanism operated by the motor cylinder B as already described. The fuel contained in the closed hoplper R being discharged through the casing into the interior of the generator beneath.

I do not limit myself to the details herein described and it will be obvious that these may be varied within the scope of the appended claims without departing from the nature of my invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. A gas producer comprising a cylinder, a s 'Jring pressed piston therein, a feed pipe for the cylinder to connect it with the exhaust of an engine cylinder, a gas generator, a fuel supply means for the gas generator, a feeding means for the fuel supply means, and means to actuate the feeding means operated by the movement of the piston.

2. A gas producer comprising a cylinder, a spring pressed piston therein, a feed pipe for the cylinder to connect it with the exhaust of an engine cylinder, a gas generator, a hopper, a feeder, and a motor mechanism driven by the piston intermittently actuating the feeder.

3. A gas producer comprising a cylinder, a spring pressed piston therein, a feed pipe for the cylinder to connect it with the exhaust of an engine cylinder, a piston rod for the piston, a gas generator, a ho per, a feeder conveying the fuel from the opper to the generator, and a worm driven mechanism for the feeder driven by the piston rod.

In witness whereof l have hereunto set my hand in the presence of two witnesses.
